Black Ops Black Screen but CoDMW 2 works fine?

i have not recently updated to the latest LT+ firmware that came out like a week ago for the new dash board the date today is 6/29/2011 I have ran the images through abgx and both patched to trusted v2 angles both also are AP2.5 patched and recently confirmed as of 6/20/2011 but i get a black screen for black ops but call of duty MW 2 works fine and plays. WTF is going on. if one works they both should right? by the way i ran an automatic patch in abgx for the AP25 for both games. I DON'T WANT TO WASTE ANY MORE DISCS. I will try updating to LT+ latest version here probably tomorrow and then update my dashboard. any other comments might help
